Wholesome toothbrush with spreading brush part for sanitary purpose

ABSTRACT

The invention relates to the wholesome toothbrush where the brush part can be spread out by partial improvement on the brush structure previously patented with Korea Utility Model Patent No. 2000-8396 by present inventor in order to facilitate brush washing and drying by spreading plies out after using the tooth brush in the ply status of shrunken and concentrated. In accordance with the invention, this wholesome toothbrush is featured providing the brush piece mounted on front-end of the brush part with protruded part slanted upward on the top surface and the first and second mounting grooves formed systematically for having the mounting protrusion snapped therein on inner front wall of the guide sphere.

TECHNICAL FIELD

[0001] The invention relates to the wholesome toothbrush where the brushpart is spread out by partial improvement on the brush structurepreviously patented with Korea Utility Model Patent No. 2000-8396 bypresent inventor in order to facilitate brush wash and dry by spreadingplies out after using the teeth brush in the ply status of shrunken andconcentrated.

BACKGROUND ART

[0002] Looking into the toothbrush structure referred to the previousutility model patent No. 2000-8396 brush pieces where brushes areplanted is assembled, but can be disassembled, into a porous leaf springand helping out sanitary and economic use of the toothbrush withconnecting bar having a push-out button mounted on operating plate whichcontracts above brush pieces to spread out.

[0003] However above patented toothbrush has a problem with fee-motionof the brush pieces due to displacement of the push-out button whenbrushing teeth as the push-out button mounted and connected to theconnecting bar is located on the toothbrush rod and since the toothbrushcan not make rugged member on both side of brush pieces fully coveredwith above operating plate with exposed bottom member in the middle, italso has the problem with generation of displeasure caused by bumpingnoises between teeth and above rugged member when brushing teeth asother conventional toothbrushes brushing those teeth having the grip asmuch close to the mouth as possible to make the brush head parallel tothe teeth array.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] With further references to the drawings the present invention isdescribed as follows.

[0013] As shown on FIG. 1 of entire perspective view of the inventionwith partial fragmentary views, the present invention is of theconstruction composed of the flexible groove 12 to enable insertion ofprotruded guide 4 into the middle of ruling protrusions 6, 6′, the ribs11, 11′ covering main body of brush part 100 when brush pieces 2′, 2″are spread out on both side's surfaces of operating plate 300, theprimary and secondary ruling grooves 10, 10′ in step where the rulingprotrusion 6 is engaged in front of inner wall of protruded guide 4enable angle adjustment to inner direction by having fore-end ofoperating plate 300 push slanted protrusion 8 of brush piece 9 used forangle adjustment when the ruling protrusions 6, 6′ of the operatingplate 300 are ruled on the secondary ruling groove 10′, the brush piece9 used for angle adjustment and protruded on top surface of the upwardslanted protrusion 8 fixed to frond end of the brush part 100, theoperating plate 300 connected to connecting bar 8 in order to linearlyspread above brush par 100 in correspondence to the movement of push-outbutton 200 having ruling protrusions 6, 6′ protruded to both sides ofinsert guide 5 inserted to the protruded guide 4 of toothbrush rod I andabove brush part 100 combined with numbers of brush pieces 2′, 2″ inlaidto curved leaf spring 3, planted with brushes 2 therein and fixed to thefrond end of the toothbrush rod 1.

[0014] In the following drawings the number 13 with out any descriptionherein is the rugged member of the brush part 100, the number 14 is theguide surface of the protruded guide 4 and the number 15 is the thirdruling groove of the protruded guide 4.

[0015] Such toothbrush invented as described above is improved productin the function of comfortable use from previously patented toothbrushcoded as Utility Model Patent No. 2000-8396 and the further descriptionsof improved parts for their operations are disclosed below to thereference of the following drawings.

[0016] The brush part 100 is supported as the state of linear whenforegoing ruling protrusions 6, 6′ are fixed on the ruling groove 10 bymanipulating the push-out button 200 as depicted on FIG. 3 and thereofthe fore-end of operating plate 300 is placed on the starting area ofthe slanting surface on the slanted protrusion 8 of the brush piece 9used for angle adjustment.

[0017] Therefore when brushing tooth with the toothbrush constructedwith above featured technique, it can be comfortably used without anydeformation of the brush part 100 that may be generated from free-movingof the push-out button 200 as its' traverse range is located on top ofthe toothbrush rod 1 being isolated from the grip.

[0018] Also the present invented toothbrush can be used without havingany discomfort noise from bumping between tooth and rugged member asribs 1 1, 11′ are mounted on and cover both sides of operating plate 300which covers main body part of brush part 100 to hide rugged member 13of brush pieces 2′, 2″.

[0019] The present technique enables to adjust the angle of fore-end ofbrush part 100 to a certain range inward in order to clean the innerside of grinding tooth which is normally uncomfortable to brush. Theforegoing angle adjustment is enabled by inward banding of the brushpiece 9 in opposite direction to the curve of the leaf spring 3 asdepicted on FIG. 4 with its' elastic force having linear tension forcedirected to slanted surface cooperated with fore-end of the operatingplate 300 while push-out button 200 moves incorporating with the topsurface of the ruling protrusions 6, 6′ corresponded to the inner guidesurface 14 as depicted on FIG. 7b when moving the push-out button 200 tothe arrowed direction shown on FIG. 7a after isolating rulingprotrusions 6, 6′ from the ruling groove 10 by pushing the foregoingbutton 200.

[0020] Accordingly when the ruling protrusion 6, 6′ of the button 200reaches to the secondary ruling groove 10′ the button 200 is fixed to acertain position in correspondence with fore-inner wall of the guideprotrusion 4 cooperated with fore surface of the insert guide 5 when theruling protrusions 6, 6′ are mounted on the secondary ruling groove 10′by counter force of the leaf spring 3.

[0021] And therefore it facilitate the tooth brushing on inner side ofgrinding tooth by placing the brush piece 9 used for angle adjustment,and slanted inward for a certain degrees, on the inner side of thegrinding tooth.

[0022] As previously described the present invention with the brush part100 bent inward for a certain degree or as linear enables maximizedcleaning effect. To wash the present toothbrush the brush pieces 2′, 2″can be spread out by the curved leaf spring 3 of the brush part 100 whenfixing the button 200 with the ruling protrusions 6, 6′ hooked to thethird ruling groove 15 by corresponding hind surface of the insert guide5 and rear-inner wall of the guide protrusion 4 by moving the push-outbutton 200 to the arrowed direction as shown on FIG. 5.

[0023] The push-out button 200 of the present invention was designed tofacilitate easy assembly utilizing the flexible groove 12 in order toinsert guide protrusion 4 into the middle area of the ruling protrusion6 as depicted on FIG. 7 and once it is assembled the button 200 is freefrom separation.

INDUSTRIAL APPLICABILITY

[0024] As foregoing description of a preferred embodiment of theinvention explained, the present invention prevents inconvenience usefrom displacement of the push-out button as its' traversing part islocated on top of the toothbrush rod being isolated from the grip,facilitates to brush the inner side of grinding tooth by having thebrush piece used for angle adjustment mounted on fore end of the brushpart, prevents bumping noise between tooth and rugged member by havingthe ribs covering the body of the brush part mounted on both sidesurfaces of the operating plate and facilitates assembling thefunctioned part by having flexible groove in the middle part of theruling protrusion.
